Plastic flooring composition.



UNITED STATES PATENT OFFICE.

LOUIS I FLECCHIA, OF PHILADELPHIA, PENNSYLVANIA.

PLASTIC FLOORING COMPOSITION.

No Drawing.

To all whom it may concern:

Be it known that I, LOUIS FLncorna, a subject of the King of Italy, and a resident of the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful In1- provements in Plastic Flooring Composi tions, of which the following is a specification.

This invention relates to improvements in plastic compositions for use in the manufacture of fioorings and the like, and specifically to a composition which may be applied directly to a floor, stair tread or other portion of a structure in a plastic state or as a mastic.

In the manufacture of compositions of this character it has hitherto been found impossible to produce a compound which may be readily applied, as with a trowel, and will set rapidly, and which will combine with these features non-inflammability, great resiliency, good color and gloss. It is also essential that the composition shall adhere firmly to surfaces such as wood, metal, plaster, and the like, and shall be waterproof. It is the object of this invention to provide a coating composition which will fully meet the requirements just mentioned.

The ingredients of my composition are finely ground asbestos, dry mineral pigment, white lead, Japan varnish, asphaltic varnish and linseed oil. For a red color these in gredients are used in proportions substantially as follows.:' finely ground asbestos 300 pounds; finely ground dry pigment 170 pounds; white lead 40 ounds; Japan varnish 71} gallons; asphaltic varnish 6 gallons, and linseed oil2 gallons. The total amount of pigment materlal thus approximates 200 pounds. These ingredients are thoroughly mixed, forming a composition of the consistence of a mastic or paste. The propor tions named may be modified to produce variations in gloss, speed of settin depth of color, and the-like, it being note however,

that more than a half, or approximately three fifths of the body of the composition Specification of Letter: Patent.

Serial 110. 111,753.

consists of finely ground asbestos and the remainder of finely ground mineral color, the ingredients and proportions of which may be varied to obtain the color desired. Thus, with a yellow color or pigment, the amount of white lead may be reduced to 10 pounds, and of the asphaltic varnish to about 1% gallons; with a black color the white lead may be entirely omitted.

The combined vehicles are present in this composition in such proportions as to produce a pasty mass or mastic of proper consistency to be readily applied by means of a trowel or the like. The proportions of the ingredients thereof may be varied to some extent in accordance with the gloss and speed of setting desired, or such other considerations as may present themselves, and the proportion of combined vehicle to body may be varied as required by the specific character thereof to produce a proper plasticity. Such a plastic mass, having a plaster'like or pasty consistency such as adapts t for ready application with a trowel or the like, is called a mastic throughout the specification.

This composition may be applied by means of a trowel or other device directly to wood, metal, brick, plaster, fabric, or the like, and adheres firmly thereto. In the case of outdoor wooden floors of poorly seasoned lumber, and liable to swellor contract to an excessive degree, the composition is preferably applied to a burlap or other fabric cover stretched thereover. Where a relatively thick coating is desired, it may "-be applied in successive layers, of which,

where the surface desired requires a relatively expensive pigment, the ground layers may be made with a less expensive body pigment.

On application the composition sets rapidly, and is completely hardened within twenty-four hours. The surface produced is of good and pure color and has a permanent It is non-inflammable and waterproof. It is very resilient, absorbing shocks and reducing noise to a great extent.

gloss.

I claim: I 1. Aplastic composition comprising ground asbestos to approximately 300 lbs; pigment, finely ground, approximately 200 lbs; 5 Japan varnish approximately 7% gals; asphaltic. varnish approximately 6 gals. and linseed oil approximately 24 gals.

2. A plastic composition containing ground asbestos, 300 pounds; dry pigment, 170

ounds; white lead, 40 pounds; Japan varg LOUIS FLECCHIA.
